My invention relates to an improvement.

in keyless automobile clocks of the type shown in my pending application No. 755,539 filed March 19, 1913, the object being to adapt the clock of that application to be mounted in automobiles having in place of the ordinary dashboard, an over-hanging hood known as a cowl-board.

With these ends in view, my invention consists in a keyless automobile clock having certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claim.

In carrying out my present invention, the cyllndrical clock-case body 2 is provided at its forward end with a relatively wide, annular mounting-fiange 3 located in a plane at a right angle to the axis of the clock and furnished with screw-holes at by means of which the flange is screwed directly to the cowl-board (not shown) which is furnished with a circular opening large enough to have the case 2 set into it, whereby the clock is suspended, as it were, by the flange 3 in the cowl-board instead of being attached in the ordinary manner by its rear end to the front of a dashboard.

The body 2 of the case being located back of the cowl-board when my improved clock is installed as described, special means must be provided for manually shifting the windmgand-setting mechanism of the clock from its winding to its setting adjustment, and vice versa, my improved clock belonging to that class of keyless clocks in which the shifting of the mechanism from winding to setting, and vice versa, i not effected by laterally moving the rotary winding and setting ring. For this purpose, I form the flange 3 at a point centrally below the clockdial 5, with a segmental slot 6 receiving the stem 7 of a knurled button 8 standing just in front of the flange, this button being mounted in the bent outer end of an operating-lever 9 which extends through a slot 10 in the lower face of the case 2. The inner end of this lever is cut away to form a fork 11 adapting it to fit over and rock upon a spacing-sleeve 12 mounted upon the universal pillar 13, and interposed between the rear movement-plate 141 of the powertrain and the forward movement-plate 15 thereof, as shown in Fig. 7. A sleeve 16 mounted upon the sleeve 12 and shorter than the same by the thickness of the yoke 11, is provided for preventing the lateral displace ment thereof upon the sleeve 12. the yoke being held between the forward edge of the sleeve 16 and the rear face of thc'plate 15, as shown in Fig. 7.

The operating-lever 9 is formed with a cam surface 1'? engaging with the adjacent edge of the rearwardly turned arm 18 of an oscillating gear-carrying yoke 19 provided with a fixed hollow stud 20 furnished at its engagement with the pinion 28 by means 5 interposed between the outer face of the yoke and the inner face of the spacing.- shoulder 21 of the stud 20 which latter turns freely upon a short spacing-sleeve 23 mounted directly upon the universal pillar l3 and interposed between the front face of the front-movement plate 15 of the power-train and the inner face of the rear movementsplate 24 of the independently organized time-train having a corresponding front movement-plate 25. The yoke 19 is also provided with a solid stud 26 carrying an oscillating winding-and-setting driven wheel- 27 constantly in 'mesh with the driven wheel 22 and carrying upon its outenface' an oscillating winding-and-setting pinion 28 normally in mesh with the removable main winding wheel 29 which has a square opening for the reception of the projecting outer end of the winding-arbor 30, the said wheel 29 being supported in position for of a removable washer'Sl resting upon the front face of the front movement-plate 15 of the power-train as shown in Fig. 2.

The yoke 19 is normally held in its winding position in which it is shown in Fig. 3, by a spring 82 fixed to the rear face of the frontmovement-piate 1-5 of the power-train and engaging with a pin 38 carried by the yoke 19 and projecting through a segmental slot 34 in the said plate 15. To limit the swinging movement of the yoke 19, I mount in ita stop-pin 35 which travels in a slot 86 in the plate 15, the said pin engaging with the ends of the slot, whereby the oscillating movement of the yoke 19 is limited. The winding arbor 80 carries an ordinary spring barrel 37 furnished at its forward end with a main wheel 38, the arbor being furnished at its projecting rear end with a winding ratchet 39 engaged by a spring pawl 40.

The driven wheel 22 is constantly in mesh with the teeth 41 of the yvinding-and-setting gear 42 which has rotary bearing upon the edges of the rear and front movement-plates 24'and 25 of the independently organized, removable time-train, whereby the said gear is centered with relation to the said movement. For preventing the lateral movement of the gear 42, its teeth 41 are interposed and ride between two spacingrings 48 and 44, shown in Fig. 6, and particularly described in my before mentioned pending application. A bent spacing-ring 45 interposed between the spacing-ring 44 and the reanface of the rear movement-plate 24 of the removable time-movement, is employed to prevent the forward movement of the gear .42. The removable time-movement (0011-.

tained between the plates 24 and 25 is constructed and utilized in accordance with the instructions of my prior application referred to, and need not be described here.

Upon the projecting forward end of the ear 4,2, I mount a bezel-carrying ring 46 ormed upon its rear edge with a flange 47 fittingbpver the forward edge of the clockcase dy 2. The forward edge of the bezel-carrying ring 46 is formed with an externally threaded flange 48 upon which the bezel 49 is screwed. The bezel carries the usual crystal 50 which holds the dial-mat 51 in place u on the dial 5 which in turn restsupon a ial-baok 53 which rests upon short studs 54 secured to the front face of the front movement-plate 25 of the removable time-movement. A s ace 56 between the dial-back '53 and the ont movementplate 25, receives ordinary dial-work compr-ising a cannon pin-ion 56 (Fig. 2) driving a dial-wheel 57 carrying a dial-pinion 58 which meshes into and drives the socketwheel 59. The said dial-wheel 57 is meshed. into by a wheel 60 mounted upon the forward end of a short shaft 61 ournaled in the movement-plates 24 and 25 and furnished at its rear end with a wheel 62 arranged in position to be meshed into by the pinion 28 mounted on the stud '26 carried by the yoke 19, when the same is swung into its setting position against the torsion of the spring 82, by means of the operatinglever 11. 1 1

Under normal conditions, 111 .im oved keyless clock is ready for win ing 37 the simple rotation of the bezel 49 from left to i right, whereby the teeth 41 of the internal gear 42 operate to rotate the winding wheel 29, and hence the arbor 30 upon which the main spring (not shown) within the barrel 37 is wound. To set the clock, the button 8 is seized by the fingers and shoved from left to right, whereby the operating-lever 9 is turned upon the sleeve 12 as upon a fulcrum and its cam surface 17 caused to engawith the arm 18 of the yoke 19 and swmg the same against the tension of the s ring 32 and thus demesh the pinion 28 mm the wheel 29 and cause it to mesh into the wheel 62 connected with the dial work of the timemovement and thus rotate the hands. During the operation of setting, the button 8 must be constantly held to the limit of its movement to the right. hrs soon as this pressure is removed, the-sp ing 32 acts to swing the yoke from left to right whereb the pinion 28 moves from the wheel 62 bac into engagement with the wheel 29.

In a rim-winding keyless clock, the combination with a clock-case provided toward its front end with an annular mountingflange located at a right angle to the axis of t e clock ease and providing for suspend- 10 an operating member passing through the said flange and manually operable from the front thereof, for shifting the position of the said osciliatin member;

In testimony W ereof, I have signed this specification in the presence of two sub- 15 scribing witnesses.
